2769. Find the Maximum Achievable Number

Problem Link

Description

---

Given two integers, num and t. A number is achievable if it can become equal to num after applying the following operation:

• Increase or decrease the number by 1, and simultaneously increase or decrease num by 1.

Return the maximum achievable number after applying the operation at most t times.

 

Example 1:

Input: num = 4, t = 1

Output: 6

Explanation:

Apply the following operation once to make the maximum achievable number equal to num:

• Decrease the maximum achievable number by 1, and increase num by 1.

Example 2:

Input: num = 3, t = 2

Output: 7

Explanation:

Apply the following operation twice to make the maximum achievable number equal to num:

• Decrease the maximum achievable number by 1, and increase num by 1.

 

Constraints:

• 1 <= num, t <= 50
